.SH NAME
hdifftopam - convert horizontal difference image to original PAM image
.UN synopsis
.SH SYNOPSIS
\fBhdifftopam\fP[\fIpamfile\fP]
[\fB-pnm\fP]
[\fB-verbose\fP]
.PP
Minimum unique abbreviation of option is acceptable. You may use
double hyphens instead of single hyphen to denote options. You may
use white space in place of the equals sign to separate an option name
from its value.
.UN description
.SH DESCRIPTION
.PP
This program is part of
.BR "Netpbm" (1)\c
\&.
.PP
\fBhdifftopam\fP undoes what \fBpamtohdiff\fP does.
.UN options
.SH OPTIONS
.PP
In addition to the options common to all programs based on libnetpbm
(most notably \fB-quiet\fP, see
.UR index.html#commonoptions
Common Options
.UE
\&), \fBhdifftopam\fP recognizes the following
command line options:
.TP
\fB-pnm\fP
This option tells \fBhdifftopam\fP to create a PNM image (i.e. PGM or
PPM). Without it, \fBhdifftopam\fP creates a PAM image (with a
tuple type of "unhdiff"). If the PAM does not have the proper depth
to be a PGM or PPM (i.e. 1 or 3) and you specify \fB-pnm\fP,
\fBhdifftopam\fP fails.
.TP
\fB-verbose\fP
Print output image width, height, depth and maxval to standard error.
